|Title:||Bale starting chamber with tensioning device|
|Abstract:||A round baler for forming round bales of crop material includes side-by-side belts trained for movement between a starting position and a finish position around a series of stationary rollers including a forward baler roller and a rear baler roller spaced apart from the forward baler roller. Upper and lower roller arrangements are continuously engageable with the crop material. The upper roller arrangement, the lower roller arrangement and a run of the belts extending between the forward baler roller and the rear baler roller together define a starting baler chamber. A belt tracking and tensioning device is interposed between the forward baler roller and the rear baler roller. The belt tracking and tensioning device is mounted on the upper roller arrangement, and functions to maintain the belts in a predetermined relationship relative to the upper roller arrangement and to increase the tension of the belts in response to bale growth, as the belts move between the starting position and the finish position.|
